Do you think VFR codes could be changed for countries that are different to 7000, e.g., Australia 1200?
Found this on Wiki :
This is what I found on the Airspace Infringement :
Set your transponder to ON/ALT. If a specific code has not been given to you by ATC, set code 1200 in Class E or G airspace and code 3000 in Class D airspace (for VFR flights).
So should be 1200 not 7000.
1200 for australia US canada only.
7000 is the standard if no specific code exists in a country
